I'd been burning CDs in Music Disc Creator (EMC9) all day and all of a sudden I can't burn anything. I set things up as usual, press the BURN button and get one of two messages: "Seek, synch, ATIP or mechanical positioning error- Unit not ready" or "Drive not ready-Unit not ready". Both of them end with the message (Insert Disc). Needless to say there IS a disc in the drive.
I swapped out the blank disc for another blank disc, I powered the computer down, I tried burning through another program in EMC9 but still get the same response.
The computer is only 3 months old. What has happened? (And even more important, how can I fix it?)
